While he clung to Peter and John, all the people, utterly astounded, ran together to them in the portico called Solomon’s. And when Peter saw it he addressed the people: “Men of Israel, why do you wonder at this, or why do you stare at us, as though by our own power or piety we have made him walk? The God of Abraham, the God of Isaac, and the God of Jacob, the God of our fathers, glorified his servant Jesus, whom you delivered over and denied in the presence of Pilate, when he had decided to release him. But you denied the Holy and Righteous One, and asked for a murderer to be granted to you, and you killed the Author of life, whom God raised from the dead. To this we are witnesses. And his name—by faith in his name—has made this man strong whom you see and know, and the faith that is through Jesus has given the man this perfect health in the presence of you all.

“And now, brothers, I know that you acted in ignorance, as did also your rulers. But what God foretold by the mouth of all the prophets, that his Christ would suffer, he thus fulfilled. Repent therefore, and turn back, that your sins may be blotted out, that times of refreshing may come from the presence of the Lord, and that he may send the Christ appointed for you, Jesus, whom heaven must receive until the time for restoring all the things about which God spoke by the mouth of his holy prophets long ago.”

See what kind of love the Father has given to us, that we should be called children of God; and so we are. The reason why the world does not know us is that it did not know him. Beloved, we are God’s children now, and what we will be has not yet appeared; but we know that when he appears we shall be like him, because we shall see him as he is. And everyone who thus hopes in him purifies himself as he is pure.

Everyone who makes a practice of sinning also practices lawlessness; sin is lawlessness. You know that he appeared in order to take away sins, and in him there is no sin. No one who abides in him keeps on sinning; no one who keeps on sinning has either seen him or known him. Little children, let no one deceive you. Whoever practices righteousness is righteous, as he is righteous.

As they were talking about these things, Jesus himself stood among them, and said to them, “Peace to you!” But they were startled and frightened and thought they saw a spirit. And he said to them, “Why are you troubled, and why do doubts arise in your hearts? See my hands and my feet, that it is I myself. Touch me, and see. For a spirit does not have flesh and bones as you see that I have.” And when he had said this, he showed them his hands and his feet. And while they still disbelieved for joy and were marveling, he said to them, “Have you anything here to eat?” They gave him a piece of broiled fish, and he took it and ate before them.

Then he said to them, “These are my words that I spoke to you while I was still with you, that everything written about me in the Law of Moses and the Prophets and the Psalms must be fulfilled.” Then he opened their minds to understand the Scriptures, and said to them, “Thus it is written, that the Christ should suffer and on the third day rise from the dead, and that repentance for the forgiveness of sins should be proclaimed in his name to all nations, beginning from Jerusalem. You are witnesses of these things. And behold, I am sending the promise of my Father upon you. But stay in the city until you are clothed with power from on high.”

Commentary

“That we should be called children of God. Jesus is God’s child by nature and essence as the eternally begotten Son; we become God’s ‘children’ by grace through Spirit-wrought faith in him (Jn 1:12). Here an epexegetical clause answers the question ‘what kind?’ posed by the interrogative above. ‘Children’ makes no reference to chronological age, but features instead the parent-child relationship. Young or old, it matters not. All begin this earthly life when they are conceived as ‘children,’ and they continue to be this, continue to be someone’s ‘children,’ for the rest of their lives. The moniker that God gives, then, means far more (see 2:1 and 2:12–14). Behind John’s language, observes Loader, lies ‘an awareness that no human being has a claim to be God’s child. The author is not operating within a framework of thought which sees all God’s human creatures as his children by virtue of their creation (as, for instance, Acts 17.28). Being God’s child in I John means being given a privileged relationship which one does not naturally deserve’ (William R. G. Loader, The Johannine Epistles, Epworth Commentaries [London: Epworth, 1992], 33)” (p. 317).
